摘要： This paper describes using NIRS to determine CP,NDF,RS,VC in Chinese cabbage (Brassica campestris L.ssp pekinensis).Two hundred and forty-two samples of Chinese cabbage were collected from the main producing areas in China for calibration and prediction of the four constituents above.The results of calibration showed that the multiple correlation coefficients between NIRS and chemical methods were 0.9958,0.9852,0.9821 and 0.9814,and the standard errors were 0.398,0.134,0.098 and 0.51,respectively.The correlation coefficients of prediction were 0.994,0.978,0.974 and 0.981,and standard errors were 0.353,0.127,0.108 and 0.548,respectively.These results indicate that NIRS can be used to determine the four constituents of Chinese cabbage as accurately as chemical methods.
